Antimicrobial and Antioxidant activity of Echinops emiliae (Asteraceae)

Handan Şapcı, Cem Vural, Servet Özcan


The aim of this study was to investigate the antimicrobial and antioxidant activities of different extracts from Echinops emiliae Schwarz ex P. H. Davis. Antimicrobial activity was estimated against several common human pathogenic bacterial strains using the agar disc diffusion and minimal inhibitory concentration assays. Antioxidant activity was evaluated using the total flavanoid and total phenolic content methods. On the light of these experiments, E. emiliae would seem to be an important natural antioxidant. Antimicrobial and antioxidant of E. emiliae have not been reported up to now. The results of this study obviously reported that the antimicrobial and antifungal activity could be change with used extracts. Also, the micro dilution method was more sensitive than disk diffusion. This study is first report on the biological activity of E. emiliae as regarded endemic species from Turkey. The results show that E. emiliae could use in the treatment of some illness.
